Application filed September 19, 1913. Serial No. 790,741.

T all 'whom 'it may concern Be it known that l, SQUIER l/VILDER, acitizen of the United States, residing at Huntingdon, in the county ofCarroll and State of Tennessee, have invented a new and usefulCultivator, of which the following is a specification.v v

The device forming the subject matter of this application is acultivator of the cylinder type.

rihe implement is adapted to be employed forv cultivating andpulverizing soil about diierent sorts of crops, such as corn, cotton,potatoes and the like, and, in general, under all conditions in which amachine of the character hereinafter described maybe employed toadvantage.

@ne object of the invention is to provide means for moving the cylinderin a direction parallel to its axis, so that the cylinder may work at agreater or less distance from the standing row.

l1`he invention aims to provide novel means for rotating the cylinder.

1t is within the province of the invention to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

1n the accompanying drawings z--Figure 1 shows in front elevation, acultivator con structed in accordance with the present invention, partsbeing broken away; Fig. 2 is a top plan of the cultivator, portionsbeing broken away and sectioned; Fig. 3 is a cross section on the lineS-3 of Fig. 2, portions being broken away; Fig. 4 is a perspective ofthe cylinder together with a portion of its supporting shaft; Fig. 5 isa sectional detail illustrating a portion of the clutch mechanism.

1n carrying out the invention and referring particularly to Figs. 1 and2 for a general understanding of the structure, there is provided awheel mounted main frame including a tongue 1 supporting a seat 2. Secured as indicated at 3 to the tongue 1 is an arched axle 4, thehorizontally disposed, outwardly projecting ends o-f which are denotedby the numeral 5. rlhe main frame of the machine includes a rear crossbar 6 held in place upon the tongue 1 by means of a clip 7 and bolts 8.Adjacent its ends and in its upper edge the rear cross bar 6 is equippedwith notches 9. A front cross bar 10, somewhat shorter than the rearcross bar 6, forms a portion of the main frame and is held in place uponthe tongue 1 by means of a clip 11 and bolts 12. rllhe front cross baris sustained by means of rearwardly extended converging braces 14,secured as indicated at 15 to the tongue 1, the forward ends of thebraces 14 being connected with certain of the bolts 12.

rThe invention includes two duplicate mechanisms, located upon oppositesides of the machine, and but one of these mechanisms will be set forthin detail.

Journaled for rotation upon one of the ends 5 of the arched axle 4 is adrive wheel 16 which, as best shown in Fig. 3 comprises a rim 17, spokes18 and traction teeth 19 projecting from the rim. The spokes 18 of thedrive wheel 16 support a shoulder 20 to which is secured a sprocketwheel 21. Mounted to swing upon the end 5 of the axle 4 is a frame whichis a composite structure, the frame comprising a pair of angularsupports 22, the rear ends of which receive the part 5 of the axle 4, asFig. 3 will most clearly show. Adjacent their apices, the angularsupports 22 are equipped with vertically adjustable bearings 23controlled by screws 24 or in any other suitable manner.

Journaled in the bearings 23 is a shaft 25. Mounted to rotate upon theshaft 25 and held in place against transverse movement by pins 29 asshown in Fig. 5, is a sprocket wheel 26. About the sprocket wheel 26 andthe sprocket wheel 21 is trained a sprocket chain 27. The hub of thesprocket wheel 26 is indicated at 28 and is equipped at its inner sidewith a clutch 30. Mounted to move upon the shaft 25 longitudinally ofthe same is a clutch 31. y1`he teeth of the clutch 31 are adapted tocooperate with the teeth of the clutch 30 and between certain teeth ofthe clutch 81, one pin 29 on the shaft 25 is received. By moving theclutch 31 longitudinally of the shaft 25, the sprocket wheel 26 may becoupled up with the shaft 25 so that when the drive wheel 16 is rotated,motion will be transmitted through the c held in place in sprocket wheel21,'the sprocket chain 27 and the sprocket wheel 26 to the shaft 25,*tothe end that rotationY may be imparted to the pulverizing cylinder to bedescribed hereinafter. In the periphery of the clutch 31 there isformeda groove 32. Coperating with the groove 32 in the clutch 31 isarearwardly extended lever 35 mounted loosely on a fulcrum pin 34 carriedby a cross bar 33 extended between the angular supports 22. This lever3.5v is adapted to be moved in the direction of the arrow A in Fig. 1and may be engaged with the notches 9 in the rear cross bar 6, thefunction of the lever 35 Abeingto shift the clutch 31 into and out ofengagement with the clutch 3 0 on the sprocket wheel 26. Y

Secured to the outer end of the shaft 25 is a sprocket wheel 36.receiving a sprocket chain 37 trained around a sprocket Wheel 38secured to a shaft 39 journaled in a bearing 40 which is secured to thelower, forward ends of the angular supports 22. The inner end of theshaft 39 is squared as shown at 41 and mounted on the squared portion 41of the shaft, adjacent the inner extremity thereof is a pin 42 which isshown most clearly in Fig. 1.

A pulverizing cylinder, shown in Fig. 4 is provided and this cylinder ismounted upon the squared portion 41 of the shaft 39 to slide thereon inthe direction .of the axis of the shaft but to rotate along with theshaft; The pulverizing cylinder may be variously constructed but in thepresent instance it is shown as comprising a pair of disks 43 and 44 andan inner band 45, spaced Vfrom the disk 44. The disks 43 and'44 and thevband 45 are peripherally connected by a plurality ofslats 46 whichdefine acute angles with the axis of the shaft 39. The slats 46 carrylpulverizing teeth 47 which may be any desired manner.

It will now be understood that from the shaft 25 rotation is imparted tothe shaft 39 and the pulverizing cylinder 43-44-45 through the medium ofthe sprocket wheel 36, the sprocket chain 37 and the sprocket wheel`38.

A means is provided for moving the pulverizing cylinder 43-44-45longitudinally Yof the squared portion 41 of the shaft 39 rand with thisend in view, a spool 48 (shown in Figs. land 2 but omitted in Fig. 4) isattached to the disk 43, the spool 48 receiving the forked end of alever 49 which is fulcrumed as shown at 50 upon the end portion 5 of theaxle 4 to swing in the direction of the arrow A in Fig. 1.` Bymanipulating the lever 49, the cylinder 434445 may be adjustedlongitudinally of the shaft 39, for the purpose hereinbefore set forth.

In order that the pulverizing cylinder 43-44-45 may be raised andlowered along with the frame comprising the angular supports 22, asshown in Figs. 1 and 3.

ports 22 and the connections 33 and 40 therebetween, a lever 51 isfulcrumed at 52 upon the end of the front cross bar 10, there being alink 53 which connects the forward end of the lever 51 with one of theangular sup- A locking device 54 of any desired construction may bemounted upon the cross bar 6 for holding the lever 51 in adjustedpositions.

The operation of the structure has been -set out step by stephereinbefore but briefly considered is as follows z-The pulverizingcylinder 43-44*45 is rotated by a gear train comprising the drive wheel16, the sprocket wheel 2l, the sprocket chain 27, the sprocket wheel 26,the shaft 25, the sprocket wheel 36, the sprocket chain 37, the sprocketwheel 38 and the shaft 39. The sprocket wheel 26 is coupled upoperatively with the shaft 25 by manipulating the lever 35. Thepulverizing cylinder 43-44-45 is moved longitudinally of the shaft 39through the medium of the lever 49. The pulverizing cylinder 43-44`45may be raised and lowered by tilting the frame comprising the angularsupports 22 through the medium of the link 53 and the lever 51.

Although the implement has been shown as comprising duplicate mechanismsof the sort hereinbefore described, it is obvious, notably from Figs. 1and 2, that one pulverizing cylinder may be employed as advantageouslyas two.

Having thus described the invention, what is claimed is 1. In acultivator of the class described, a main frame including an axle; aground wheel on the axle; an auxiliary frame pivoted upon the axle andhaving angularly related portions extended downwardly and forwardly withrespect to the axle; a sprocket wheel mounted to move with the groundwheel; a primary sprocket wheel journaled on the lower end of thedownwardly extended portion of the auxiliary frame; a secondary sprocketwheel journaled for rotation at the angle between said frame portions,the sprocket wheels on the auxiliary frame acting as weights fordepressing the forward end of the auxiliary frame; a soil engagingelement operatively connected with the primary sprocket wheel; asprocket chain forming an operative connection between the primary andsecondary sprocket wheels; a sprocket chain forming an operativeconnection between the secondary sprocket wheel and the sprocket wheelwhich is mounted to move with the ground wheel; and means for raisingand lowering the forward end of the auxiliary frame with respect to theaxle.
